AUTOMATIC HEASURING DEVICEFOR LIQUIDE.

Application led October 21, 1926. Serial No. 143,165.

My invention relates to an automatic ymeasm-ing device for liquids, and has for its object to provide a means for delivering predetermined quantities of liquids in a simple Vand direct manner, particularly so as t'o pipvlde such a means whereby two ditterent quantities may be predetermined by the valve apparatus, either one of which quantities may be drawn ott" at the option of the person operating the valve. y

` lVith the above and other objects in view, my invention, consists'in the combination and arrangement of parts hereinafter described and claimed, it being understood that, within the limits of what is claimed, changes in the precise embodiment shown, may be made without departing from the spirit of the invention.

In the drawings- Figure 1 is a sectional view of a liquid container having my invention applied thereto;

Figure 2 is a front elevation of the same, partly in section;

Figure 3 is a section alon(r the line 3-3 of Figure 1. showing atopman view ofl my device with parts thereof shown in section;

Figure 4 is a section along the line 4--1 of Figure 1. i

Figure 5 is a detail of the automatic air valve.

Referring now more particularly to the drawings, A refers to a container for liquids, such as a cream urn. having provided therein the false bottom 10. Positioned beneath the false bottom are two measuring compartments B and C. The said compartments may be of any capacity-according to the option of the pelson constructing the device, but in the embodiment shown, the compare ment B is shown larger than the compartment C, thus. thelcompartment B might be or one pint capacity and the compartment yC of one-half pint capacity. A portion of the false bottom 10 is depressed to form a seat 11 for the cylindrical plunger vulve D and is continued up and over the said plunger valve as at 12, so as to thereby form a` cylindricalhousing E in which is slidably positioned the said (plunger valve D. The tongue 14, positione on the plunger valve D, is adapted to slidably engage the slot 13 provided medially the upper surface of the housing E, lwhereby the vsaid plunger valve D is prevented from rotating in Ythesaid housing.

vpipe 18 hereina The scat 11 has provided therein and near the inner end thereof, the ports 15 com municating the urn A with the measuring compartments B and C; the said ports being opened by the plunger valve D when in its "outward position and closed when the said plunger valve is in its inward position. The seat 11 also has provided therein and near the outer end thereof, the ports 16, and the ,upper portion 12 of the housing E has pro vided therein, directly above the said ports 16, the ports 17 'communicating with the iter described. The ducts 19 are provided in the plunger valve D suitably to communicate the ports 16 withthe ports 17 when the said plunger is in its inward position.

Provided in the false bottom 10 and communieating the measuring compartments B and C with the vertical pipes 20, is the aperture 21 formed on its underside suitably to receive the Stoppers 22, the said Stoppers being constructed of cork or other buoyant ma terial and provided with the rubber seat 23 on the upper side of said stopper. The upwardly extending stem 24 is positioned on the stop er 22 and passes through the guide 25 positioned in the pipe 20, the upper end of the said stem being formed into the loop 26 so as to limit thev downward travel of the said stem and stopper. The upper end of the pipe 2O communicates` with the bifurcated pipe 27 passing upwardly through ythe urn A and coxmnunicating with' the atmosphere.

Atlixed to the front Walls of the measuring compartments B and C is the valve structure F having vertically positioned therein the rotatable plug 28 positioned in the plug seat 32 and rovide with the discharge duc-t 29 passing upwardly therethrough and extending at right angles suitably to register with the ports 30 and 31, the port 30 communicating with the measuring compartment B and the port 31 communicating `with the measuring compartment C; the said ports opening` into the plug seat 32 diametrically opposite each other, whereby the said discharge duct 29 may handle 23.v

In the operation of iny device, the urn A containing fthe uid toe be measured. is caused tocommumcatewith the measuring compartments B and C, bymoving the plunger valve D outwardly so as to uncover the ports 15, whereupon liquid will 119W into the said compartments, the displaced air being permitted to pass out through the l aperture 21, and pipes 2O and 27 to the atmosphere; but when the compartments are tilled with the liquid, the bouyance of the stoppcrs 22 will causethem to rise and close the apertures '21 whereby entrance of the' -ing the plug 28 suitably to communicate.

thedischarge ductk 29 `witl1 the port 30 and compartment B or the port 31 and compartment C at the option of the person using the device.

It is obvious that as the evel of the liquid falls in the compartment, the stopper 22 will descend and open the aperture 21 suitably for a repetition ofthe before described sequence of operations` but until the said stop per has thus descended and opened the aperture 21, the port 16. duct 19 and port 17 willI serve to prevent a vacuum being formed in the compartment.

I claim:

, 1. The combination withv an urn provided with a' false bottom, of a plurafity ofmeasuring compartments positioned beneath the said false bottom, a valve seat formed in said false bottom, a housing formed over said valve seat. a plunger valve slidably positioned in said housing, ports provided in said seat and near the inner end thereof communicating said compartments with said urn, ports provided in said seat and near the outer end thereof and communicating with said compartments, ports provided in said housing above said second mentioned ports,

with said measuring compartments, means for communicating said third mentioned ports with said pipes, ducts provided in said plunger valve connnunicatino said second mentioned ports with said tlnrdy mentioned portsl` when said plunger valve is in its inner position whereby said compartments may be maintained at atmospheric pressure when liquid is being withdrawn from said compartments, guides positioned in said pipes, vertically extendin stems slidably positioned in said guides, dependent stop ers positioned on said stems suitably to cose said apertures 1vvhen in their upward position, the said Stoppers being constructed of buoyant material, so as to tioat upward when liquid is admitted in said compartments. whereby displaced air may be permitted to escape to the atmosphere but any liquid prevented from entering said pipes; and means `for causing the optional discharge of any ofv said compartments.

2. The combination with an urn provided with a false bottom` of a pluraity of measuring compartments positioned beneath the said false bottom, a valve seat formed in said false bottom, a housing formed over` said valve seat` a tplunger valve slidably positioned in saidv housing; means 'for communicating said urn with the said measuring compartments for filing the same, by the outward movement of said plunger valve; buoyantly operable means for communicating said measuring compartments, when being `l filled, with the atmosphere. whereby said com artments mav be shut olf from the atmospiiere when filled andthe measured quantity of liquid retained'in said compartments; means for communicating said measuring compartments,4 when being filled, with the atmosphere by the inward movement of said plunger valve; and means for causing the optional discharge of any of said compartments.

In testimony vvhere'ot` I affix my signature.
